Laim Param No. 102,442, mail April 26, 1870.

The Schedule referred to in these Letters Patent and making part of tnesame.

To all whom it may concern.-

Be it known that I, J AMES A. SINCLAIR, of Woodsfield, in the county ofMonroe and State ot' Ohio, have invented a new and useful Improvement inPumps; and l do hereby declare that the following is a full, clear, andexact description ofthe same,.reference being had to the accompanyingdrawings making a part of' this specification, in which the figure is asectional elevation.

This invention has for its Object to drive water, contined in a chamberin a well, to the surface, by creating atmospheric pressure in thechamber above the water.

The invention consists in the combination of an air-chamber placed inthe water in a well, and communicating therewith by means of pipes, withone pipe extending to the surface, for the escape of Water, another pipeleading downward from the surface for the supply of' air to the chamber,a stationary piston ou the airpipe,and a cylinder sliding over thepiston, for tbe collection and compression ot' air.

In the drawing- A is the chamber within the well, constructed f' metalOr other suitable material. w

a a, the pipes by which water enters the chamber.

b, the pipe by which water risesI from the chamber to thesurface.

c, the pipe by which air is forced downward into the chamber A.

d, a stationary piston or disk on the upper end of the air-pipe c, witha central orifice, through whichthe air-pipe passes, l

e, a cylinder fitted to the rim of the piston d, so as' to slideup anddown thereon under the action of the lever h, to which thecylinder-stern is jointed.

i is a globe-valve in the pistou el, Opening upward.

k is a slide over the lower mouth of the orice in the piston, in whichthe valve i lies, by which slide the amount of air passing through theglobe-valve is regulated. Y

On lowering the cylinder, the air between it and the piston is irce'dinto the pipe c, and down into the chamber. A. lf one stroke of thecylinder does not create sudicient pressure in the chamber A to forcewater out of it, on raising the cylinder a fresh supply of air enters itthrough the valve t', and at the next down stroke more air sent into thechamber.

. The lower end of theair-pipe is to be furnished with a bulb orcylinder, l, within the main chamber, and provided with valves, forletting water into the cylinder under the atmospheric pressure outsideit.

The chamber A Should be placed so low in the well as to keep the valvesOf the inner cylinder always uuder water, else the compressed air willescape through them.

If either of the pipes b c is made in two pieces, the coupling may beeffected by taperingr the contiguous ends, and burying them in` a block,m, and fastening them therein by keys n passing through the block,l andoccupying notches in the sides of the pipes'. 'The pipes may, however,be made each of one piece.

The advantage of a cylinder sliding over a xed piston is, that' thelatter' is thereby protected from contact with all external matter.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is

rlhe combination of the chamber A, inclosed bulb or cylinder l, pipes i1c, stationary piston d, and mov able cylinder e, all constructed andarranged to operate as set forth.

JAMES A. SINOLAIR.
